According to TMZ, Whitney Houston was found with her face underwater in a bathtub. She was taking Xanax at the time which may have caused her to drown.

She was getting ready for a pre-Grammy's party when she wouldn't respond to knocking on the door. When a stylist checked on her after being in the bathtub for over an hour, she screamed, a bodyguard came in to pull her out of the bathtub. Paramedics arrived shortly there after.
